There are 3 data sets given as

I) x 7 8 9 10 11 12 13 Total

Frequ 1 2 1 2 2 0 2

Mean dev|x-10|*f 3 4 1 0 3 0 6 17

II) x 7 8 9 10 11 12 13 Total

Frequ 2 3 0 0 1 1 3

Mean dev|x-10|*f 6 6 0 0 1 2 9 24

III) x 7 8 9 10 11 12 13 Total

Frequ 0 0 4 4 1 0 1

Mean dev|x-10|*f 0 0 4 0 1 0 3 8

Thus we find the middle one Jason has the highest deviation.
